GEORGE JONES, OF CHICAGO, ILLINOIS.

SELF-FEEDING HEATER.

SPECIFICATION .forming part of Letters Patent l'o. 359,678, dated March 22, 1867.

Application filed August 1, 1886.

To aZZ whom it may concern.:

Be it known that I, GEORGE Jones, residing at Chicago, inthe county of Cook and State of Illinois, and a citizen of the United States, haveinvented a new and useful Improvement in SeliFeeding Heaters, of which the follow` ing is a full description, reference being had to the accompanying drawings, in which- Figure l is a vertical section of the upper end of a steamheater with my improvement attached thereto. Fig. 2 is a detail, being a vertical section of my device with the cover and valve open. Fig. 3 is a side elevation showing my device with the cover and valve closed. Fig. Zhis aview of the pin upon which the valve is located. Fig. 5 is a modification showing my device attached to a self-fecding stove. Fig. 6 is a plan of m5' device as attached to astove.

The object ot my invention is to provide an improved means oi' releasing the accumulated gas in the `fuel-nieganines ot selfieeding heaters, and thus preventing its ignition or escape into the room when the magazine is opened to replenish it with fuel. This object I accomplish by providing` the heater or stove with an attachment having a passage for fuel, which can be closed both at the top and bottom, and having a gas-chamber outside thereof, from which a pipe leads to a chimney, a damper being provided in the pipe which is automatically opened and closed by the opening and closing of the coverol` the attachment, as illustrated in thc drawings.

In the drawings, A represents the upper end of a steam heater, c being the steamchamber.

B is a fuetmagazine, which in use extends downward as far as required. Its upper end is provided with a Bange, b, which rests upon a shoulder at the top of the heater, as shown in Fig. l.

C is my attachment, which is secured tothe top of the heater by bolts c, only one of which is shown in the drawings. These bolts c also serve the purpose of securing parts of the heater together. The attachment C is provided with a central passage, D, which opens into the top of the magazine B, the lower end of the passage being somewhat smaller in diameter than the top of the magazine, leaving Serial No. 210,250. (No model.)

a space, d, between the two. Outside of D and surrounding the same is a chamber, e, into which gas can pass from the magazine B.

f is a removable piece or stopper adapted to close the lower end of the passage D, and it is provided with a handle.

gis ahinged cover at the top ofthe pas sage D.

h is a. short piece of pipe communicating with the chamber e and adapted to receive a pipe, which leads therefrom to a chimney.

i is a damper in the pipe It.

j is astandard projeeting upward from the cover g.

it is a short rod provided, as shown, with a screw-thread at each end` Z are sockets into which the screwthreaded ends of the rod k pass. One of these sockets is pivoted to the projection j, and the other is pivoted to the upper end of a lever, on, the lower end of which is connected with a rod, n, upon which the damper is placed, the rod n being pivoted, as usual, inthe walls of thepipe.

As shown, the cover g is so hinged to Cthat when the cover is opened a given distance its movement will be arrested by a stop, o.

The operation is as follows: ./Vhcn fuel is to be fed to the magazine B, the cover g is to be opened, and as it is opened the damperz' will also be opened and brought into the position shown in Fig. 2. Then any gas which may have accumulated in the chamber e and in the magazine can pass oft" to the chimney through 7L. Then the part f can be removed and fuel be put into the magazine through the passage D without inconvenience or danger from gas.

In Figs. 5 and 6 my improvement is' shown attached directly to the top of a stove, F, provided with a fuel-magazine, G. My attachment, as shown in these figures, is secured in place by means of bolts p, which pass through a flange, g, at the lower end, and also through a ilange, r, upon the top of the magazine, and through another iiange, s, upon the inside of the stove-body. In these gures a cover, H, which corresponds with the cover g of Fig. l, is pivoted to the top of the attachment and swings in a horizontal plane, and the position of the damper in h. is changed to correspond, and it is operated automatically by the bar or lever t, as represented in Figs. and 6. henV the cover His closed,the damper will be closed, and asthe cover H is swung around the damper will be opened, t being provided with a slot at one end, and being pivoted at one end to the stove-cover, and at the other being connected with the pin upon which the damper is located.

Vhat I claim as new, and desire to secure by Letters Patent, s

In a self-feeding heater, the combination of the fuel-magazine B, the attachment C, located above the fuel-magazine, and provided with a central fuel-passage, D, having its lower end 15 of less diameter than the top of the fnel-niagazine, and a gas-chamber, e, surrounding said Y
